1031 Exchange- selling one of two properties in Exchange

[Seth Mitchell]

Hi all, I have two properties that were part of a 1031 exchange I completed a few years ago (sold one property, bought two). They are now in an LLC, and I am looking to sell one of those two properties in order to purchase 1-2 others. So I have two questions: Are there any restrictions or tax liabilities to essentially splitting a previous 1031 exchange to do another? And secondly, I have a relatively small mortgage (around $100K) on the property in question, and would likely buy one property without a mortgage (as is undeveloped land), and the other with a mortgage. Due to the mortgage requirements to maintain the same level of debt or more, could I theoretically pay off the entire mortgage before selling the 1031 property to that my next property(s) would not necessarily need to also have mortgages to qualify for a 1031? Any advice would be greatly appreciated- thanks!
